A large rectangular baler is provided with a crop material feeding arrangement including curved duct defining a pre-compression chamber from which a pre-compressed crop material charge is ejected, through an inlet of a baling chamber, by a stuffer arrangement. The duct includes a rear section curved about a horizontal, transverse axis and a stuffer frame, that carries a reciprocable tine arrangement, is mounted for rotation about this axis. A double acting injection cylinder reciprocates the tine arrangement between retracted and extended positions, respectively, wherein transversely spaced tines are withdrawn from, and extended into, slots provided in a top wall of the duct rear section. A double-acting hydraulic lift cylinder is provided for controlling the pivoting of the frame for effecting lifting of a pre-compressed charge of crop material and ejecting it through the baling chamber inlet.
